Product Details

The SPEC SB154 Stage 4 Clutch Kit is an extreme-performance clutch system engineered for heavily modified engines demanding maximum torque capacity and instantaneous pedal engagement. Designed for competitive motorsport applications, this kit delivers aggressive, no-compromise clutch performance where lightweight rotating mass and rapid lock-up are essential.

Key Features:

  • High-clamp performance pressure plate for maximum clamping force
  • 3, 4, or 6 puck carbon semi-metallic friction disc for aggressive engagement and high heat resistance
  • High-torque rigid hub and carrier assembly for direct, solid power transfer
  • Includes release bearing and installation tool kit for a complete, ready-to-install package
  • Lightweight construction reduces rotating mass for quicker throttle response

Intended Driving Applications:

  • Drag Racing
  • Drifting
  • Road Racing
  • Rallye
  • Pulling
  • Circle Track

Please Note: The SPEC Stage 4 clutch features a harsh, race-oriented engagement characteristic and is not recommended for street use. This kit is intended for dedicated competition vehicles operating in high-demand motorsport environments.

Best price to be found, no ridiculous shipping costs.

I got the part I ordered and will be having someone install it soon looks just fine and I love the chat feature as well.. thinking about buying brake shoes now.. a lot of savings

Great prices & fast shipping.

They had the best price anywhere on the items I ordered(Recon Lights). Prompt emails and accurate tracking via UPS shipping. I'm pleased and will order more items now that I know they're "legit". Thanks Autoplicity!<br><br>Nick C.

GOOD SERVICE, FAST SHIP, CHEAP PRICE

I ordered this product and Wednesday in the morning and it was on my door step Thursday morning with regular shipping. The ordering process was super easy and the price was $35 cheaper than any other online retailer. The Rack is awesome, easy to assemble took me about 20 minutes by myself, put on my jeep hooked up the bikes and off I went, fantastic design, I highly recommend the Rola NV2 bike rack and highly recommend Autoplicity

Not sure if they overlooked my order but I didn't get my shipping info (3 days after ordered) until I emailed asking for status update. I received a response the following day and all my items ordered came 2 days later...much faster than I had anticipated considering the "delay" or lack thereof (5 days total). Long story short...items are as described, best prices (from what I can researched online for same items/brand) and resonable shipping prices. the selection and brand(s) offered were somewhat limited for my specific needs, otherwise I would've ordered more.

I was trying to locate a hi volocity radiator fan and for it at Autoplicity at a very good price. The item was shipped fairly quickly concidering it most likely had to come from the manufacturer. Thanks for your help.
